For enhanced safety, the front seat shoulder belts of the Audi A8 are height-adjustable to accommodate a wide variety of driver and passenger heights. A better fit can prevent injuries and the increased comfort also encourages passengers to buckle up. The BMW 7 Series doesn’t offer height-adjustable seat belts.

Both the A8 and 7 Series have child safety locks to prevent children from opening the rear doors. The A8 has power child safety locks, allowing the driver to activate and deactivate them from the driver's seat and to know when they're engaged. The 7 Series’ child locks have to be individually engaged at each rear door with a manual switch. The driver can’t know the status of the locks without opening the doors and checking them.

The A8 has a standard front seat center airbag, which deploys between the driver and front passenger, protecting them from injuries caused by striking each other in serious side impacts. The 7 Series doesn’t offer front seat center airbags.

To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the A8. But it costs extra on the 7 Series.

Both the A8 and the 7 Series have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, front seatbelt pretensioners, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, post-collision automatic braking systems, daytime running lights, rearview cameras, available night vision systems, lane departure warning systems, blind spot warning systems, around view monitors and rear cross-path warning.


From surveys of all its subscribers, Consumer Reports’ December 2018 Auto Issue reports that Audi vehicles are more reliable than BMW vehicles. Consumer Reports ranks Audi 1 place higher in reliability than BMW.


The A8’s 3.0 turbo V6 hybrid produces 15 more horsepower (335 vs. 320) and 39 lbs.-ft. more torque (369 vs. 330) than the 740i’s standard 3.0 turbo 6 cyl. The A8’s 3.0 turbo V6 hybrid produces 13 more horsepower (335 vs. 322) than the 740e’s standard 2.0 turbo 4 cyl. hybrid.

Fuel Economy and Range

To lower fuel costs and make buying fuel easier, the Audi A8 uses regular unleaded gasoline (premium recommended for maximum performance). The 7 Series requires premium, which can cost 20 to 55 cents more per gallon.

The A8 has 9.6 gallons more fuel capacity than the 7 Series Hybrid’s standard fuel tank (21.7 vs. 12.1 gallons), for longer range between fill-ups. The A8 has 1.1 gallons more fuel capacity than the 7 Series’ standard fuel tank (21.7 vs. 20.6 gallons).

Brakes and Stopping

For better stopping power the A8’s standard brake rotors are larger than those on the 7 Series:



7 Series

Front Rotors

14.8 inches

13.7 inches

Rear Rotors

13.8 inches

13.6 inches

Tires and Wheels

For better traction, the A8 has larger standard tires than the 7 Series (255/45R19 vs. 245/50R18). The A8’s optional tires are larger than the largest tires available on the 7 Series (265/40R20 vs. 255/35R21).

The A8’s standard tires provide better handling because they have a lower 45 series profile (height to width ratio) that provides a stiffer sidewall than the 7 Series’ standard 50 series tires.

For better ride, handling and brake cooling the A8 has standard 19-inch wheels. Smaller 18-inch wheels are standard on the 7 Series.

Suspension and Handling

For better handling and stability, the track (width between the wheels) on the A8 is 1.2 inches wider in the front than on the 7 Series.


The A8 has a 3500 lbs. towing capacity. The 7 Series has no towing capacity.

Servicing Ease

J.D. Power and Associates surveys of service recipients show that Audi service is better than BMW. J.D. Power ranks Audi third in service department satisfaction. With a 14% lower rating, BMW is ranked 8th.


In poor weather, headlights can lose their effectiveness as grime builds up on their lenses. This can reduce visibility without the driver realizing. The A8 has standard headlight washers to keep headlight output high. The 7 Series doesn’t offer headlight washers.

The A8 offers an optional 115-volt a/c outlet on the center console, allowing you to recharge a laptop or run small household appliances without special adapters that can break or get misplaced. The 7 Series doesn’t offer a house-current electrical outlet.

Economic Advantages

The A8 will cost the buyer less in the long run because of its superior resale value. The IntelliChoice estimates that the A8 will retain 39.71% to 40.32% of its original price after five years, while the 7 Series only retains 30.92% to 36.65%.
